Facebook trolling...?

[Janny]

Several occasions I've seen or heard about events whereas people have created fake Facebook pages under the name of a legitimate company and then replied to their customers posts/complains (i.e. Jetstar last year, Coles, Kmart, Target etc...).

Obviously they are not directly hacking, but are using their trademark names etc..
Would such companies actually take action on individuals doing this? Obviously their fake pages and deleted and banned, but beyond that what happens? Do they just let it slide and file it under the risks of operating a social media page, or are they able to work with Facebook to track down those responsible to take legal action?!

I'd be interested to hear your thoughts on this!

Cheers
